T (6 whom it may concern.-

Beitknown that I, MARY HELLEN SWIFT, a citizen of the United States,residing at Chicage, in the State of Illinois, and exec utrix of thewill of EDWARD D. SWIFT, deceased, who

was late a citizen of the United States, residing at Chicago, in theState of Illinois, do declare that said deceased invented a new anduseful Machine for the Tangential Applica- [0 tion of ReciprocatingPower for Operating Rotary Machinery, of which the following is aspecification.

This invention relates to mechanism for converting a reciprocatingmotion into rotary, and is intended more especially for use inconnection with a steam-engine or other motive power employing areciprocating piston,

but is applicable to and can be used with other reciprocating means fortransmitting power to produce rotary motion.

The objects of the invention are to obtain a positive tangentialapplication of the power to perform a rotary driving; to dispense withthe use of the ordinary crank and wrist-pin and other similar devices;to give an increase of leverage power; to prevent the waste of steam orother motive power, and consequently loss of power on that account, andto improve generally the construction and operation of the mechanism asa whole.

The invention consists in the novel features of construction andcombination ofparts hereinafter described and claimed.

In the drawings, Figure 1 is a side elevation of the mechanism of theinvention with the outer face-plate or side disk guard-ring for thewheels removed; Fig. 2, a plan view of the mechanism of the invention;Fig. 3, a

' longitudinal central sectional plan view of the mechanism; Fig. 4, aperipheral elevation of the drum; Fig. 5, a detail in sectional plan ofthe pair of acting wheels; Fig. 6, a sidewise perspective view of themechanism with the outer face-plates or side disk guards 5 and ringsremoved; Fig. 7, a sidewise perspective view from the front of one ofthe acting or driving wheels with the face-plate removed, showing thelock and friction belt or band around the drum; Fig. 8, a sidewiseperspective view from the opposite side of the wheel shown in Fig. '7.

The mechanism employs in its construction a pair of acting wheels A andA and a pair of idle or guide wheels B and B, with the wheels of eachpair in juxtaposition and in close proximity to each other and locatedand operating in the same plane. All the wheels have cogs or lugs upontheir circumferential rims or perimeters, and the wheels of each pairare of similar form and dimensions and, as shown, are arranged for thewheel A to be in line longitudinally with the wheel B and the wheel A tobe in line longitudinally with the wheel-B. The Wheels A and A aremounted in close proximity or j uxtarelation each to the other on acylindrical drum D, fixed to a shaft S so that the revolution of theWheels A and A will continuously revolve the drum and impart rotation tothe shaft for operating machinery. The wheels B and B are mounted inclose proximity or juxtarelation each to the other on the axle S so asto be in line, re

spectively, with the wheels A and A. The shaft S and each end of theaxle S are respectively supported by and adjusted in j ournals, boxes,or bearings secured to and resting upon a framework. An endless chainbelt E, having cogs or sprocket-links runs over the wheels A and B, andalike endless chain beltE runs over the wheels A and B. Each chain beltis so constructed and adjusted that its cogs or sprocket-links willengage the perimeters and cogs or lugs of the wheels over which it runs,and when the chain belt is con structed on the plan of sprocket-chainthe cogs or lugs of the wheels are so constructed as to engage thesprocket-links. One end of the arm orrod F is secured to the face of thechain belt E by a clasp or clamp g, andone end of an arm or rod F issecured to the face of the chain belt E by a clasp or clamp g, and theopposite end of each arm is secured toa crosshead on the piston-rod P ofa reciprocating piston. On the inner face of one side of each wheel Aand A a lock L L is located and so constructed and arranged as tooperate a friction-belt II, which encircles the periphery of the drum Dand constitutes apart of the lock,

and the two locks are arranged to stand in a reverse position to eachother.

Each wheel A and B, as shown, is constructed of an outer and inner partor section, the outer part or section consisting of a cylindrical rim orbody a and aface ring or plate S, and the inner part or sectionconsisting of a cylindrical rim or body a, and a face ring or plate S,with the rim or body a of the part of section S of an interior diameterand width to receive the rim or body a of the part of section S, whichis entered into the rim or body a when the parts are assembled tocomplete the wheel. The exterior face of the rim or body a has firmlysecured thereto or formed therewith cogs or lugs O, as shown in Fig. 7,

. and the face ring or plate S has its edge extending beyond theexterior face of the rim or body a, so as to form an edge flange a asshown in Fig. 8. The two plates or sections are assembled or united tocomplete thewheel by entering the rim a within the rim a and having theflange a abut against the edge of the rim or body a, and when enteredand properly assembled the wheel will have on each side an opening orhole 0 0, formed by the face ring or plate, which openings are of adiameter to receive the drum D for mounting each wheel on such drum.

Each wheel B and B, as shown, is constructed of a series of radial armsor spokes 0, extending out from ahub or center. The spokes have securedto their outer ends an annular rim a which rim has cogs or lugs O,fixedly secured to or formed upon its outer face, and through the axialcenter of the hub is a hole or bore 0 of a diameter to receive axle Sfor mounting the wheels on the axle.

Each driving chain belt E and E may be constructed of cog or sprocketlinks joined together by means of their interlocking fingers or wings,pivotally united by suitable bolts or pivot-pins, as shown.

The cross-head is secured to the piston-rod P and, as shown, has an armor bar r on one side and an arm or bar r on the opposite side of theattaching socket-head, both arms or bars being curved forwardly, givingthe crosshead a semicircular or crescent shape, with the outer end ofeach one of the arms or bars projected in a straight line.

'The arm or rod F is attached to the bar r of the cross-head by an eyeor socketf at the end of the arm or'bar and extends from the eye orsocketfon a right line 0 to the clamp or clasp g, by which its forwardend is attached to the chain belt E, on the upper side thereof. the armor bar 1' of the cross-head by an eye or socket f at the end of the armor bar and extends from the eye or socketf on a right line r to theclamp or clasp g, by which its forward end is attached to the chain beltE, on the under side thereof. The forward end of the arm or rod F is ona right line tangential to the perimeters of the wheels at their upperface, over which the chain belt to which The arm or rod F is attached toit is secured runs or travels, and the forward end of the arm or rod Fis on a right line tangential to the perimeters of the wheels at theirlower face, over which the chain belt to which it is secured runs ortravels.

The lock L L is provided for the innerface on one side of each wheel Aand A, as shown in Fig. 7, which lock consists of a segment m, securedto the inner face of rim or body (0 and to the inner side of the wheeland having its inner face parallel with a chord of the arc of the circlebounding the inner face of the rim (1, and abar n, which has the planesof its two opposite parallel sides of wedge-like form, with a leg orstud 'n at one end and a leg or stud n at the other end thereof. Eachone of the legs or studs has its inner side of bevel form, and the outerface of the bar a is so arranged as to engage the inner surface of thesegment m. Afriction-belt H encircles the periphery of the drum D, alsoforms a part of the lock. One end of the friction-belt terminates in thehead q, having an outer face of bevel form, and the other end of thefriction-belt terminates in a head q, also having an outer face of bevelform. At the central part of the friction-belt is a joint formed bycutting the belt into two parts and arranging a short curved bar Q2 tothe outer curved surface of the belt to cover or overlap the separatedends and securing the bar by proper bolts or other means, so as to givesome flexibility to the belt, or such flexibility may be produced in anyother suitable man ner. A spring 7L, also forming a part of the lock, isattached at one end to the friction-belt at K, and the other end thereofis attached to the segment on at K, and the bar a is arranged in closeproximity to the bevel-faces of the friction-belt heads, so that thebevel-face of the leg or stud n will by a slight reciprocating movementengage the bevel-face of the belt-head q, and the bevelface of the legor stud n will by a slight reciprocating movement engage the bevel-faceof the belt-head q, thereby causing the beltheads 1 and g by areciprocating movement to alternately approach and recede from eachother on the peripheral surface of the drum D.

The drum D is a hollow cylinder having a head or plate secured to oneend,which plate projects beyond the periphery of the drum and forms aflange (t on the outer side of the drum, and at the center of the heador plate is a hole 0 for the passage of the shaft S as shown. Ahead ordisk d is entered into the end of the drum, as shown, and at the centerA face-plate or circular disk guard d and is arranged to project overthe peripheral edge of the drum and has at its center a hole 0 toreceive the end of the shaft S as shown. A spring h is secured at oneend to the friction-belt H at K and at its other end to the segment m atK for the purpose of holding the belt-heads q and q to their properposition. A bar 19 is arranged at a point on the inner side of thewheels A and A in close proximity to the bar it to prevent excessivepressure on the spring h.

U is a steam-cylinder of the engine, and was represent a part of. theengine-frame, and for operation the mechanism is to be arranged andlocated in proper position and relation to the engine or other motivepower for the travel of the reciprocating cross-head and the arms orrods to move the chain belts back and forth and revolve the shaft of thedrum.

In operation the mechanism of the invention, at each reciprocatingmovement of the cross-head or other operating device each arm or rod Fand F transmits the motive power to the chain belt to which it issecured and causes a rotary movement of the wheels upon which the chainbelt runs or travels, and with such movement the lock in one wheel uponthe drum will operate and cause the inner face of the segment m toengage the outer face of the bar n, which engages, respectively, thebevel-faces of the friction-belt heads q and g, which engagement forcesthe heads into closer proximity each to the other,and thereby tighteningthe friction-belt around the periphery of the drum and locking theacting wheel to the drum to impart thereto and to the shaft upon whichit is mounted a rotary movement in harmony with the advance of theacting wheel. At the same time and with the same movement of thecross-head the other arm or rod transmitting the motive power to theother chain belt and the wheels upon which it runs or travels gives thelock in the other wheel on the drum a reverse operation and relaxing thefriction-belt from the periphery of the drum by a recession of thefriction-belt heads from each other, which unlocks the acting wheel fromthe drum, so that the unlocked acting wheel and its companion idler orguide wheel have a free rotary movement on the drum without impartingrotation to the shaft. By this mode of operation each active wheel isalternatelylocked to the drum and unlocked therefrom, and the drum andshaft are continuously operated in the same direction to transmit theprimary motive power to the operation of machinery connected with theshaft.

The motive power is applied with a greatlyincreased leverage force byreason of its application being in a line tangential to the perimetersof the acting or driving wheels for the drum.

The mechanism may be constructed of any and the diameter of the drumshould preferably be as small as practicable, The exterior of the drumpreferably is formed of a thick facing of Babbitt or other similarmaterial, upon which the wheels A and A can turn or revolve. Thefriction-belt should be of a width to produce the proper amount offriction for operative work and may be made of any suitable material andformation. The lock for the inner surface of the acting or drivingwheels A and A may be of any form of construction that will perform itsoffice of engaging and disengaging in an adequate manner the wheels anddrum. The extension arms or rods F and F may be of any adequate form,and their outer ends may be secured to the chain belts each respectivelyin any suitable manner, preferably at points equidistant from the end ofthe piston-rod. The cross-head, secured to the end of the motive-piston,may be made in any form or method adequate to hold thearms or rods eachrespectively in a suitable position for driving the chain belts runningover the wheels. The chain belts may be of any suitable form ofconstruction which will produce the required friction by engaging theperimeters and cogs or lugs of the wheels upon which they run or travel.The number of cogs orlugs formed on the perimeters of the Wheels maybeincreased or diminished, and modified as to form and dimensions, as maybe required to produce the adequate amount of friction. Thewheels A andB and A and B may be constructed in any manner competent to performtheir proper functions and preferably of like form and dimensions, itnot being intended to limit the details of construction otherwise thanpointed out in the claims. The idle or guide wheels B and B may beconstructed in a manner similar-to the acting wheelsA and A and in likemanner mounted upon a drum hung upon and fixed to a shaft, and therebybecome acting wheels. Also when deemed desirable a lock may be locatedto the inner face of both sides of each one of the acting wheels.

The bar 9t of thelock L L, referred to in the recitals of thespecification as being secured to the inner side of each'wheel A and A,is preferably so secured by means of a bolt arranged in and through aslot formed through the bar n at right angles to the inner side of thewheel and at the central part of the outer side of the bar, the innerend of the'bolt being firmly secured to the inner side of the wheel andthe outer end-of the bolt terminating with a head which projects overthe edge of each side of the slot, the bolt and slot beingso arranged asto permit the bar or to have a slight lateral movement caused byaslightreciprocating movement of' theboltin the slot. it i I claim as being theinvention for which Letters Patent are desiredr 1.
